Thanks, could you also share the output of this after the screen
freeze?

/sys/kernel/debug/dri/0/i915_edp_psr_status
/sys/kernel/debug/dri/0/i915_display_info
/sys/kernel/debug/dri/0/i915_dmc_info
/sys/kernel/debug/pmc_core/package_cstate_show

It eventually comes back from screen freeze? Like moving the mouse or
typing brings it back?
